MICHER — [Noun, Verb] A person who sneaks about for dishonest purposes or a petty thief; also, to sneak or skulk. From Middle English mycher, müchere, müchare, derived from mich ("to skulk, pilfer") + -er (agent suffix). Related to mitch ("to sneak, steal"). Unlike "lurker" (which hides to observe or wait, often without malice) or "pilferer" (which steals but not always stealthily), a micher moves with the furtive grace of a shadow slipping through a cracked door. It is the figure darting behind market stalls with pockets suddenly full, the child playing truant in the hedgerows, the hand that lifts a purse and vanishes into the crowd—proof that small betrayals, too, require their own particular craft.
